Application filed December 21, 1920. Serial No. 432,265.

tractive, ornamental appearance, and yet,

which may be conveniently utilized as a channel casing for electriclight wires leading to various points about a house.

A further object is to provide a molding designed for receiving electriclight wires, which will serve to hide the same from view, and a moldingwhich will be simple and practical in; construction, comparatively cheapto manufacture, easy to'apply to walls, and ceilings, fire-proof, lightbut substantial, and otherwise efiicientin the uses for which it isintended. With these and other objects in view, the invention consistsin certain novel features of construction, and combinationsand'arrangements of parts, as will be more fully hereinafter. described,and pointed out in the appended claims.

In the accompanying drawings Figure 1 is a fragmentary top plan 'view ofmy improved molding, with parts broken away for clearness, andillustratin two sec tions of molding connected by annter joint.

F igu the line 22 of Figure 1.

Figures 3, 4 and 5 are views similar to Figure 2, and illustratingmodifications.

Figures 6, 7 and 8 are views in transverse section of modified forms ofsealing strips.

The molding is preferably formed of a strip of bendable spring-sheetmetal, bent along longitudinal lines into the desired shape. In thepreferred form illustrated in Figures 1 and 2, the edges of the strip ofsheet metal are bent on a longitudinal line away from the flat baseportion 1 of the strip, and towards each other forming curved convergingwalls 2. The walls 2 curve gradually towards each other, and away fromthe strip, and are then bent directly back towards the strip formingparallel inner walls 3 terminating adjacent the base 1, and spacedapart-a sufficient distance re 2 is a view in transverse section on forthe ready accommodation oft he heads of screws 8. The strip is formedwith a series of centrally disposed openings '7 for the accommodation ofthese screws, or other,

suitable securing devices for fastening the strip to a wall or ceiling9.

The walls 2 and 3 constitute spring members, and form in effect, hollowbeads, which may accommodate insulated wires 4 as shown in dotted linesin Figure 2, at each edge. of the molding. The adjacent faces of thebeads, or in other words, the walls 3, are provided with oppositelydisposed aligned longitudinal grooves 5, adapted to receive a sealing orcovering strip 6, which effectually conceals the screws 8' and gives amore attractive appearance to the molding 7 p The strip 6 is forced intothe grooves.

The beads as before noted, constitute spring members, and it is merelynecessary to insert one edge. of the strip in one of the grooves 5, andforce the other edge inwardly, spreading the walls. 3 apart, and.

. permitting entrance of the other edge of the strip into the othergroove 5. The spring action of the walls will retain the sealing stripfirmly in place.

The grooves 5 and Strip 6, are common to all forms of the device, but inFigure 3, the angular shape, peculiar to the beads illustrated in theother figures is eliminated, and the beads 10 are substantiallycircular, with the exception of one flattened side formed by theparallel walls 11. The extreme inner ends of these walls are curved awayfrom each other, in arcuate form, as shown at 12.

In Figure 4, 1 illustrate a form in which the two heads 13, aresubstantially rectangular inshape, and the inner walls 14 of the beadsforming the wire receiving channel are flared apart at their extremeinner ends, as shown at 15-.

In Figure 5, the beads '16 are substantially triangular in crosssection.

The modified forms of sealing strip illustrated in Figures 6, 7 and 8,are all provided with a pair of parallel groove engaging edges 17, butin Figure 6, the intermediate portion 18 of the strip is lon itudinallybent into substantially semi-circular cross sectional shape. I p

In Figure 7, the central portion 19, is substantially U shaped in crosssection, and in Figure 8 V shaped, as shown at 20.

The modified forms of moldings and strips illustrated, are merely toindicate a few ways in which the molding can be made more ornamental. Ido not desire, however, to be limited to one or all of the'formsillustrated, as obviously the shape of the molding might be varied ininfinite ways .without departing from the spirit and scope of theappended claims.

What I claim is;

1. A molding, comprising a strip of bendable metal, the edges of saidstrip bent along longitudinal lines to form hollow spring beads adaptedto receive wires, and presenting a pair of adjacent parallel groovedfaces, said faces coacting with the intermediate portion of the strip toform a chan nel, and a sealing strip of metal having its edges locatedin the grooves.

2. A molding, comprising a strip of bendable spring metal, the edges ofsaid strip bent to form hollow spring beads, said beads forming housingsfor insulated wires and presenting a pair of parallel grooved faces,said faces coacting with the intermediate portion of the strip to form achannel, said intermediate portion of the strip having openingsthroughout its length, securing devices in the openings, a. metalsealing strip sprung into the grooves and concealing said securingdevices.
